John Gagliano, chief investigator for the New Orleans Coroner's Office, said he identified the decomposed body by Russell's dental records.

The body was found near the Rigolets, about 20 miles from an area in eastern New Orleans where Aaronne Russell and Aaronne Mitchell, 13, were last seen walking two dogs.

A second body was found Friday near Bayou Liberty, and Gagliano said his office will perform an autopsy on this body to determine the cause of death Sunday. However, the family has not yet provided dental records for Mitchell, and the coroner's office will not be able to identify the body without them, Gagliano said.
